Calcite Marble Metamorphic Rock

Marble is a sparkling and typically granoblastic rock.

Calcite marble metamorphic rock.

Black marble also occurs. Calcite is the principal constituent of limestone and marble. It is extremely common and found throughout the world in sedimentary metamorphic and igneous rocks. Marble is a metamorphic rock consisting predominantly of calcite or dolomite.

Marble is a metamorphic stone formed by subjecting limestone to heat or pressure. Granoblastic rocks have uniformly sized equidimensional anhedral grains produced by recrystallization in a solid state metamorphism. Calcite specimens can occur in metamorphic deposits igneous rocks and hydrothermal veins. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite.

Impurities produce pale gray brown or variegated colored rock. Some geologists consider it to be a ubiquitous mineral one that is found everywhere. In pure form marble consists of calcium carbonate calcite and is sparkling white. These rocks are extremely common and make up a significant portion of earth s crust.

Calcite is a rock forming mineral with a chemical formula of caco 3. In geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. It is a metamorphosed carbonate rock limestone or dolomite rock. These rocks are extremely common and make up a significant portion of earth s crust.

It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite. Calcite is the principal constituent of limestone and marble. Marble takes a high polish. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
